Obituary Farewell to Professor (1914-2011)

Aleksis one could agree or disagree – and still be good friends. He was a noble man and true scholar. His ent- husiasm, energy and diplomacy were well combined with multi–lingual knowledge, so rare in the scientific community nowadays. Aleksis Dreimanis was born into a family of tea- chers on August 13, 1914, in Valmiera, . Because of evacuation of the Rīga Alexander High School which was his father’s workplace to Saransk, in the middle part of the European Russia during World War I, Aleksis spent three years of his childhood in Saransk where he learned Russian writing and reading. The family came back to Latvia in 1920. After graduation from the Rīga First High School he started studies in the Department of Natural Science at the Mathema- tics and Science Faculty of the University of Latvia. In 1938 he finished his studies with Magister rerum naturalium degree in geology. He published his first scientific paper at the age Aleksis Dreimanis. of 21 in 1935, as a third year student. This paper was Photo by V. Zelčs, 2003. the first Latvian publication on glaciotectonics and one of the first studies in the world where glaciotec- tonic deformations were combined with stratigraphy. Aleksis Dreimanis passed into eternity at University Therefore Aleksis Dreimanis was probably the first Hospital, London Ontario on Friday morning, July 8, who distinguished kinetostratigraphic units in glacial 2011, sinking into deep sleep a day after undergoing surgery, little more than a month before his 97th stratigraphy even before Asger Berthelsen (1973) had birthday. The news of his passing seems unacceptable. proposed the idea of kinetostratigraphy. In 1939, he Aleksis was always able to change with the times, and published a method for lithologic investigation of in contact with him one tended to forget how long has the 0.5–1.0 mm fraction of tills for stratigraphical been his life’s journey. He always generously shared his purposes, later known in the Soviet literature as The knowledge and experience, and spoiled us all through Method of Dreimanis. He completed his habilitation his humane goodness, his honesty, and his loyalty. degree in 1942. Aleksis Dreimanis, born and grown up in Latvia, In his thirties Dreimanis was a classical naturalist, belongs to the Quaternary community of the world, a good combination of past and present, being at being one of its leaders whose ideas have been inclu- the same time geologist, botanist, malacologist and ded in numerous textbooks.
